High-dosed supplementation for the eye disease, AMD
- and some good dietary advice
AMD (Age-related Macular Degeneration) is a common eye disease that impairs your reading vision in particular. High-dosed supplementation with vitamin C, vitamin E, zinc and other antioxidants has been shown to help. The recommendation of these nutrients is based on documentation from a large American research project and demonstrate that normal recommendations (DRI = Daily Reference Intake) are inadequate as treatment for various disorders. There are also different foods that are highly relevant for preventing AMD or as part of a treatment against the condition.

Modern man is exposed to a lot of free radicals because of factors like stress, environmental toxins, etc. Free radicals are like “internal terrorists” that contribute to atherosclerosis, diabetes, Alzheimer’s disease, cancer, and a host of other diseases. Our only protection against free radicals are antioxidants from vitamins, minerals, and plant compounds. Antioxidants work in different ways. Being deficient in a single primary antioxidant such as selenium may leave the body vulnerable to oxidative stress and disease. What most people are unaware of is that free radicals are also essential, as they are a part of our energy turnover and immune defense. The question is how do we protect ourselves the best against infections, oxidative stress, and disease? What type of antioxidant do we get from dark chocolate, green tea, coffee and red wine? How does redox therapy with vitamin C in great quantities work on cancer patients? You can read more about these topics in the following.
Scientists from Alberta University in Canada have observed that lack of sunlight may contribute to the weight increase that many people experience during the winter period. This is because our fat cells are sensitive to sunlight. Lack of sunlight may also result in poor sleep and low levels of vitamin D, a nutrient that has other metabolic functions.
There really is no need to have an upper safe intake limit for folic acid, and we ought to enrich flour with this nutrient to prevent children from being born with potentially disabling or life-threatening brain or spinal cord defects. This is part of the conclusion of a new study from Queen Mary University of London, and it supports an earlier study from Aarhus University in Denmark. Folic acid deficiencies, which are rather common, may lead to fatigue, poor memory, dementia, and a number of other health problems later in life. It is therefore important that we focus on this essential nutrient.
Magnesium takes part in over 300 different enzyme processes, some of which are relevant for the nervous system. Magnesium deficiencies are common, and there is a link to the increased prevalence of subjective anxiety and stress. Researchers from the University of Leeds in Great Britain have reviewed a number of studies that show how supplementation with magnesium may help in cases of mild anxiety, stress, and depression. Magnesium appears to be a precondition of a healthy and sturdy nervous system, and getting enough of this nutrient is therefore important for preventing these conditions.
More than 25 percent of people older than 65 years have low levels of vitamin D in their blood. Deficiencies in vitamin B12, folic acid, and iron are also common. This is the conclusion of a large study that was conducted by scientists from Helmholtz Zentrum in Munich, Germany. The widespread lack of vitamins and minerals among older people is critical, especially because this population group is increasing. The lack of essential nutrients affects the calcium uptake, immune defense, and nervous system among other things, leaving older people increasingly vulnerable to osteoporosis, influenza, dementia, and a host of other diseases that impair quality of life and burden the entire public health sector.
Atherosclerosis is one of the leading causes of death in the Western world, and the heart is particularly vulnerable. According to a study from the University of Birmingham, Alabama (USA), foods that are rich in potassium such as bananas, potatoes, avocado, and almonds protect against this disease, which takes years to develop. Beware that too much salt and the use of diuretics may deplete the body’s potassium stores.
Fish oil contains the omega-3 fatty acids, EPA and DHA, which are important for normal development of the baby’s brain and immune defense. Pregnant women who eat oily fish several times a week help their babies against developing asthma later in life. Oily fish and fish oil supplements have similar effects. This was shown in two studies from the University of South Florida in Tampa, USA. However, pregnant women should avoid predatory fish like tuna that contain mercury. For those who dislike the taste of fish or who simply do not eat enough, fish oil supplements are an option.
Earlier studies have shown that zinc plays an important role for our health and for preventing esophageal cancer. However, it has been a puzzle to science to understand how zinc protects against this widespread cancer form. Now, Professor Zui Pan and a team of researchers from the University of Texas at Arlington, USA, have identified the mechanisms through which zinc protects healthy cells and prevents cancer cells from spreading in the esophagus. The scientists behind the new study believe that zinc given in the right dosages has a great potential for helping to prevent the disease and serving as an adjuvant in therapy. Their study is published in The FASEB Journal.
